The space shuttle Endeavour took its final flight this week — completing an aerial tour around California and a special detour over Tucson, AZ, to commemorate its last commander, Mark Kelly, and his wife, former Arizona Rep. Gabrielle Giffords. After 25 missions, 299 days in space, and 123 million miles, the space shuttle's final destination is the California Science Center in Los Angeles. As Endeavour settles into its new permanent home, we're coveting these unique Etsy finds that pay homage to space shuttles and brave explorers everywhere.
